IFT= Interferential therapy

• 

IFT= The principles of Interferential therapy were first introduce by HO Nemec( an Austrian scientist). Interferential therapy is also known as Nemec current.

•Interferential therapy is a form of electrical treatment in which two medium frequency current are used to produce a low frequency effect. • IFT is a kind of medium frequency current. • 2 medium frequency current to produce low frequency current. •Ift is used for both pain relief and stimulate the muscles and reduce swelling and inflammation which can cause pain.

BEAT FREQUENCY :_. The interference produced by two currents in this tissue is called the beat frequency. = 100 Hz this is therapeutic value.

• 

METHOD AND USES. • skin clean •Any lesion covered by jelly. • Electrodes placed accurately. • sectrum= Rectangular, Traingular,Trapezoid • Current in I and II measured. • Intensity to minimum. • Off apparatus.

ADVANTAGE. •patient cannot be given higher doses in low frequency therapy apparatus like faradic stimulator. • No sensory nerve sensation • No burning sensation. • Useful in producing relief till depth. • Localised the current in specific area

PHYSIOLOGICAL EFFECT. • pain relief •Blood flow increase. •Reduction of edema. •Motor stimulator. •Relaxing muscles spasms. •Innervated muscles contraction. •Relief of chronic pain. •Low back pain. •Periarthritis shoulder.

CONTRAINDICATION. •Cancerous lesion. •Pregnancy ( the trunk and pelvis during pregnancy). •Allergies to gel. • when cause is not known. •The anterior aspect of the neck.

INDICATION. • pain relief. •muscles stimulation. •Increased blood flow. Reduction of edema. •Re- education of deeply situated muscles. •promoted tissue healing.
